The function V(x)=x^3-6x^2 represents the volume (in cubic inches) of the box shown. The function W(x) = V(12x) represents the volume (in cubic inches) when x is measured in feet. Write a rule for $W$W . Then find W(2)
W(x) = ?
W(2) =?

W(x) = V(12x) = 123x3 - 6·122x2 = 1728x3 - 864x2 inch3
x = 2 feet, then W(2) = 1728·8 - 864·4 = 10368 inch3
